36
A Krypton atom has 36 protons and 36 electrons each.
There are zero unpaired electrons in a krypton (Kr) atom because it has a completely filled electron shell with 8 electrons in the outermost energy level.
The atom of xenon (Xe) is larger than the atom of krypton (Kr) because xenon has more electrons and a larger atomic radius.
There are 2 electrons in the highest occupied energy level of a neutral strontium atom, as the electron configuration of strontium is [Kr]5s^2.
Look at the periodic table, do you see the 36 above the Kr? This is the atomic number. The atomic number represents the number of protons in an atom. This number is unique to each element a Kr atom will always have that number of protons.
The neutral atom with 44 electrons is ruthenium (Ru).The electron configuration of ruthenium is: [Kr]4d75s1.The number of electrons in shells is: 2, 8, 18, 15, 1.
In the Rb atom, the electron configuration is [Kr]5s^1. This means there is 1 electron in the 5s sublevel of the Rb atom.
t is Selinium, Se the third member of oxygen family
Krypton (Kr) is a noble gas located in Group 18 of the periodic table. It has a total of 8 valence electrons, as elements in this group typically have a full outer electron shell. This configuration contributes to Krypton's chemical stability and low reactivity.
Tin typically has a configuration of [Kr] 5s^2 4d^10 5p^2 when it is a neutral atom. If tin forms an ion by losing two electrons, it would have a configuration of [Kr] 5s^2 4d^10, as it would lose its two outermost electrons from the 5p orbital.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
An atom of strontium has 38 electrons, which are distributed across different electron shells based on the aufbau principle and the rules of electron configuration. Strontium, with an atomic number of 38, has electrons filling up to the fifth energy level or electron shell. Therefore, there are five electron shells containing electrons in an atom of strontium.
